MAX153
1Msps, µP Compatible, 8-Bit ADC with 1µA Power Down
MAX1531Msps, µP-Compatible,
8-Bit ADC with 1µA Power-Down
General Description
The MAX153 high-speed, microprocessor (µP)-compatible,
8-bit analog-to-digital converter (ADC) uses a half-flash
technique to achieve a 660ns conversion time, and digitiz-
es at a rate of 1M samples per second (Msps). It operates
with single +5V or dual ±5V supplies and accepts either
unipolar or bipolar inputs. A POWERDN (power-down)
pin reduces current consumption to a typical value of 1µA
(with 5V supply). The part returns from power-down to
normal operating mode in less than 200ns, providing large
reductions in supply current in applications with burst-
mode input signals.
The MAX153 is DC and dynamically tested. Its µP interface
appears as a memory location or input/output port that
requires no external interface logic. The data outputs use
latched, three-state buffered circuitry for direct connection
to a µP data bus or system input port. The ADC’s input/
reference arrangement enables ratiometric operation.
